DAVID FULLER, OF FULLERSBURG, ASSIGNOR 'lO R. FULLER AND RICHARD FOOTE,OF CHICAGO, ILLINOIS.

Specification forming part of Letters Patent No. 220,524, dated October14, 1879; application filed June 23, 1879.

To all whom tt may concern Be it known that I, DAVID FULLER, ofFullersburg, county of Du Page, and State of Illinois, have invented anew and useful Improvement in Washing-Machines, of which the followingis a specification, reference being had to the accompanying drawings,illustrating the device. j

The object of. the present invention is to provide a washing-machinewith .vertical reciprocating pounders, to be operated in a box orwash-tub, the construction of which shall be cheap, durable, andefficient in removing dirt from clothes.

The nature of the invention consists in connecting-rods pivoted to thepounder-rods, and operated by a two-crank shaft, the latter beingprovided with two bea-rings on a line with its journals, to serve asguides for the upper and slotted ends of the pounder-rods, whereby thelatter are kept invertical positions by the aid of simple bearingsattached to the tub or box in which the washin g is done.

My improvement differs from the washingmachine patented to DavidJennings on March 14, 1876, inasmuch as he uses a stationary guide-barfor directing vertically the movement of the pounder-rod, whichguide-bar has a distinct function from that of the crank, and is no partthereof,-whereas in my improvement the pounder-rods are guided by thesame shaft, which gives to them a reciprocating ver- *tical movement,thus greatly cheapening the cost of this kind of washing-machine, whileits efficiency is retained.

It also differs from the washing-machine patented to T. Q. Frost,December 17, 1867, in that Frosts washing-machine has a stationaryguide-bar to direct the movement of the pounder-rods, and uses aseparate and distinct crank-shaft for operatingthe pounders, unlike mycrank-shaft, which both operates and guides the pounder-rods.

In the drawings, Figure 1 is a side elevation of a washing-machineembodying my improvements with one standard broken away to show theparts more clearly. Fig. 2 is an end elevation thereof with the end ofthe wash-box removed. Fig. 3 is a broken plan view of Fig. l; Fig. 4, abroken enlarged section of one of the connecting-rods with therecoil-spring and cap in position.

A is an ordinary water-tight box, in which the clothes to be washed areplaced. To the sides of this box are attached vertical standards B, toform bearings for the shaft C to rotate in. This shaft is bent to formtwo cranks, D, which drive the connecting-rods E, and to form the guidesD D on a line with the shaft C proper, and to form side guides, Z Z.

The pounder-rods I I are slotted out at their upper ends, so as to havevertical reciprocating movements in the guides D D'.

The cranks D and the side guides, Z Z, prevent the connecting-rods fromhavin g too much lateral play.

The pounder-rods I I are fitted to have a free reciprocating movement ina guide, G, which, with the guides D', constructed as set forth, keepthe pounder-rods in a vertical position.

The connecting-rods E E are pvoted to the pounder-rods I I at d, so thatby turning the shaft C, by means of acrank, P, or other power, thepound'ers J J will alternately be brought down ou the clothes in the boxA.

The guide G is held in place between cleats I-I on standards B and thetop of box A, pins -c being put through the parts in the ordinary mannerto keep the guide from sliding out edgewise.

I am aware that pounders (two or more) have been operated by mechanismto wash clothes by the pounding process. I therefore conue myself to theconstruction for holding the pounder-rods in a vertical position.

The clothes, in suitable thickness, are to be drawn lengthwise in thebox as the dirt is removed.

I claim and desire to secure by Letters Patent- The shaft C, bent toform cranks D and guides Z, in combination with connecting-rods E andslotted pounder-rods I I, guided by the parts D of the shaft C and theguide G in a washing-machine, as and for the purpose set forth.

DAVID FULLER.
